Abstract
About 50% of patients with progressive muscular dystrophy have a cardiomyopathy, manifested commonly by tachycardia, but also by arrythmias, refractory congestive heart failure and sudden death. Studies from the literature report manifold but nonspecific electrocardiographic changes in 41% to 85% of patients with progressive muscular dystrophy. The principal lesion is a diffuse myocardial fibrosis with minor degenerative changes in myocardial fibres unaccompanied by significant inflammation. The heart is enlarged and has a prominent deposit of epicardial fat. The myocardium is pale, coarse, flabby and friable, often showing gross evidence of scarring. The dilated chambers often contain mural thrombus.
